What is the current through a wire if 240 coulombs of charge pass through the wire in 2.0 minutes?

Answer : Current flowing, I = 2 Ampere

Explanation :

It is given that,

Charge passing through a wire, q = 240 coulombs

Time taken to pass the charge, t = 2 minutes = 120 seconds

Electric current is defined as the ratio of the electric charge divided by time taken to pass the charge.

Mathematically, it can be written as :

Putting the value of q and t we get:

I = 2 Ampere

So, the current passing through the wire is 2 Amps.

Hence, this is the required solution.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
